The device and technical characteristics of engines At the time of the start of sales, it was possible to buy a Renault 19 with a carburetor. However, we do not cover this equipment option in our guide, as very few were sold in Germany. Renault 19 engines differ not only... Есть 1 comment
Separate engine elements Before starting work on the repair and maintenance of the engine, find and remember the designations of its most important parts and assemblies. Rear view of the C-engine (looking in the direction of travel) 1 - air...
Engine lubrication system The F-engine lubrication system looks the same as the C-engine shown in this picture 1 - valve lever axis; 2 - camshaft; 3 - crankshaft; 4 - oil filter; 5 - oil pump with oil intake pipe. In the engine, oil is necessary...
Engine ventilation system A normally operating engine releases from 50 to 70 liters per minute of combustion products into the crankcase. The resulting excess pressure must be reduced so as not to overload the crankcase gaskets. The gases...
Engine check for leaks 1. Inspect the engine from above and below. 2. Small oil leaks are not dangerous, some engines emit a small amount of oil during operation. 3. Pay attention to oil stains under a parked car and obvious oil leaks. 4....
Running in a new engine Renault recommends for modifications of Renault 19 with a gasoline engine not to allow high engine speeds for the first 1000 km, and for diesel modifications - the first 1500 km. Only after driving 3000 km (for vehicles...
Engine life The service life of engines with a small volume is much shorter than with a large volume, due to the fact that the former are almost constantly operated at maximum load. With proper operation and timely routine...
Rated and maximum speed An internal combustion engine develops the most power at a certain speed; this is called the rated speed. Increasing the engine speed above the nominal speed does not result in an increase in power. The maximum...
Measurement of compression in cylinders Measurement of compression in the engine cylinders allows you to determine the degree of tightness of valves and piston rings. Engine power, easy starting in cold weather, oil consumption and fuel consumption, as well...
Cranking the engine to top dead center (TDC) The figure shows the mark of the top dead center (TDC) on the clutch housing and on the flywheel of a car with a gasoline engine (drawing on the left), and diesel (in the picture on the right). If «0» - the mark on the...
Valve clearance The individual parts of the valve train, and above all the valve stems, stretch and elongate as the engine heats up. Therefore, for the normal operation of the valves, a small gap is required between the camshaft and...
Checking and adjusting valve clearance MOT No. 45 Since the 16-valve engine is equipped with hydraulic lifters, it does not require valve clearance adjustment. In this case, in the Renault service plan, there is no work to check and adjust the clearance in...
Camshaft Drive Chain Replacement Tags (5) crankshaft sprockets (4) and camshaft (1) should look exactly at each other on the C-engine. 1 - Camshaft - gear; 2 - Camshaft drive chain; 3 - Chain tensioner. Only for C-engine The ringing sound of the engine...
Toothed drive belt Timing mechanism drive on engines of type «F» carried out using a toothed drive belt. It rotates the camshaft with a gear ratio of 1:2. Depending on the type of engine, the intermediate shaft of the oil pump drive is...
Checking the condition of the toothed belt The belt must be free of oil stains and free of cracks. The ingress of water and oil leads to the rapid destruction of the belt. The teeth of the belt must not be worn. To inspect the entire length of the belt, rotate...
Checking the tension of the toothed drive belt 1 — an asterisk of a gear drive belt of a camshaft; 2 - Tension roller; 3 - Coolant pump drive pulley. The picture shows the timing belt of a 1.8-litre petrol engine. To check the tension of the belt, press on it (see...
Toothed belt replacement The toothed drive belt is replaced in accordance with Renault recommendations after 120,000 km of run. We recommend that the toothed drive belt be replaced much earlier, as a broken or stretched belt can cause serious...
Possible malfunctions Cylinder head gasket Symptoms Reason and features A. The coolant level keeps dropping A small amount of coolant enters the combustion chambers. This can happen without visible signs of malfunction for a long time B....
Cylinder head Elements of the valve timing mechanism on a 1.8-liter engine 1 - tension roller of the toothed belt; 2 - toothed drive belt; 3 - a pulley of a gear belt of a drive of a camshaft; 4 - camshaft; 5 - a glass pusher with an...
Bearing damage Engine knocking that gets louder as the engine heats up, and therefore when the oil thins, almost always indicates bearing damage. Bearing damage can be caused by: Insufficient lubrication due to too low oil level....
Removal and installation of the engine Preparation Engine type «WITH» can be removed from the engine compartment without the gearbox. Engine type «F», on the other hand, must be removed with the gearbox. In this case, the necessary device is a lifting block...
Engine Troubleshooting Troubleshooting The checks described below assume that the engine has no mechanical damage, but has stalled and will not start. For a diesel engine, the main condition is that the engine warms up when starting up until...
